Biotrickling filter for treating volatile organic waste gas

The present invention relates to a BTF used for dealing with the volatile waste gas, belonging to the field of treatment of the volatile waste gas, which aims at solving the problems that the prior BTF has uneven air flow distribution and biomass distribution, high center gas speed and voltage drop, and the prior BTF is easy to be blocked. The technic proposal is that: the volatile waste gas passes through an intake pipe (1) and then comes into a biofilter (22), and then being drained away by an exhaust pipe (9) after having the processes of degradation and purification; a nutrient solution (11) comes into the biofilter (22) through a nutrient solution shower (18) and a dropwise adding distributor device (19) having fixed quantities at fixed time; the present invention is characterized in that adopting a light and cheap packing (4) with different grain diameters, the biofilter (22) takes a homocentric column shape sleeve structure , the grain diameters of the filled packing (4) from the center to the edge are distributed from small to big, the centre area is filled with the packing (4) with small grain diameters, the ring area of the around close walls is filled with the packing (4) of big grain diameters. The present invention makes the distribution of the biomass in the biofilter even, thereby fully utilizing the useful space of the biofilter.

Method for preparing konjak weight-losing fondant

The invention belongs to the field of nutritional health food and particularly relates to a method for preparing a konjak weight-losing fondant. The fondant mainly comprises the following components:konjaku flour, milk powder, cane sugar, starch syrup and flavor. The method comprises the steps of adding water in the cane sugar, heating and dissolving the cane sugar, filtering the cane sugar to obtain a filtrate A; adding water in the konjaku flour and the milk powder, heating the mixture to the temperature of 85-90 DEG C for dissolving; simultaneously mixing and filtering the solution to obtain B; pouring the starch syrup and B into A; heating, mixing and decocting the mixture and taking out the mixture at the temperature of 114-115 DEG C; subsequently cooling the mixture to the temperature of 70 DEG C; adding the flavor and uniformly mixing the mixture to obtain C; pouring the C into a grinding tool; and pouring the C as masses; and after cooling and solidifying the masses, baking the masses for 12-24 hours under the temperature of 35-60 DEG C, and packing the masses to obtain the finished product. The prepared product has extremely low heat, strong water absorption, large viscosity and high expansion rate, can expand by 20-100 times after entering the stomach and absorbing the gastric juice, generate satiety feeling, sufficiently meet the eating sense and does not increase weight simultaneously, and does not need to diet purposely so as to achieve equilibrium dieting, thus realizing ideal weight-losing effect.

Oil deposit purification sewage sand-carrying filling sand prevention method and sand prevention pipe column

The invention relates to an oil deposit purification sewage sand-carrying filling sand prevention method and a sand prevention pipe column. The method comprises the following steps of 1, putting the sand prevention pipe column provided with a top packer in a predetermined position in a well, conducting packing, and opening a filling sand adding channel; 2, with oil deposit purification sewage withthe viscosity of 1.4-1.6 mPa.s as sand-carrying liquid, mixing the oil deposit purification sewage with quartz sand with the particle size of 0.4-0.8 mm according to the sand-carrying ratio of 3-15%,and afterwards, conducting positive squeezing and filling; 3, conducting releasing, and backwashing remaining sand in a pipe. According to the method, the oil deposit purification sewage with low viscosity serves as the sand-carrying liquid, the risks of sand blocking and sand burying are reduced, successful sand adding is ensured, and the construction requirement for low-sand-ration filling sandprevention is met. The sand-carrying liquid is the purified thickened oil sewage of an area where a construction well is located, has good compatibility with stratum liquid and stratum minerals, avoids the situation that chemical reactions are caused and sediments clog stratum pores, and is wide in source, cheap and low in cost.
